Africa’s young population, rising internet use and rapid digitisation make a compelling case for more digital infrastructure. But investors financing data centres, fibre and cloud capacity need more than potential: they need customers, predictable workloads and revenues capable of supporting long-term investment.

Africa’s digital infrastructure investment case often begins with demographics.

The continent has the world’s youngest population, hundreds of millions of internet users, fast-growing digital financial services markets and increasing demand for cloud computing, streaming, e-commerce and artificial intelligence.

The assumption is straightforward: more users will consume more data, requiring more fibre, data centres and computing capacity.

But there is a gap between digital demand and bankable infrastructure demand.

For investors committing hundreds of millions of dollars to assets expected to operate for decades, the focus is not how many people want to use digital services. It is whether that demand can generate sufficiently predictable revenues to justify the investment.

That distinction emerged during discussions at ITW Africa in Nairobi, where infrastructure operators and investors repeatedly returned to a basic question: is underlying demand in African markets sufficient to support the scale of investment the continent requires?

The answer was broadly yes –  but with important qualifications.

Hyperscalers need more than population

Large cloud and data centre investments are typically supported by substantial customers prepared to make long-term commitments.

That creates a particular challenge in African markets.

During the discussion, the importance of banks and governments as anchor customers was highlighted, particularly for hyperscalers accustomed to significantly larger contracts in more mature markets. Policies that encourage financial-sector data to migrate back into domestic infrastructure, alongside the consolidation of government workloads in local data centres, can provide the long-term demand needed to support investment.

This makes the composition of demand as important as its size.

Millions of consumers using messaging applications or social media clearly demonstrate digital adoption. But a hyperscale data centre cannot be financed on internet-user numbers alone.

What investors need are workloads.

Banks processing millions of transactions, governments digitising public services, telecommunications operators running network applications, fintech companies scaling payment platforms and large enterprises moving applications into the cloud create the sustained computing requirements that can translate into infrastructure utilisation.

The investment equation therefore runs deeper than population growth: digital adoption creates workloads; workloads create utilisation; utilisation creates predictable revenues; and predictable revenues make infrastructure bankable.

Government can become an anchor customer

Governments occupy an unusual position in this equation.

They make policy, regulate markets and procure enormous amounts of technology themselves.

That means government can stimulate digital infrastructure investment not only by offering incentives but also by becoming a customer.

The discussion pointed to the migration and consolidation of government data into domestic data centres as one mechanism for creating the long-term demand needed to support infrastructure investment. Financial-sector localisation policies could have a similar effect by increasing the volume of banking and payments workloads hosted locally.

This is increasingly relevant as African governments pursue data-sovereignty and cloud policies.

Nigeria, for example, is developing its National Sovereign Cloud Initiative, while the Central Bank has introduced data sovereignty requirements for the financial sector. Such measures signal an intention to retain more critical workloads within the domestic infrastructure ecosystem.

If implemented effectively, policies of this kind can have an economic consequence beyond data governance: they can create anchor demand.

A government migrating ministries, agencies and public digital services onto domestic cloud infrastructure represents a potentially substantial customer. So does a financial sector moving critical workloads into local data centres.

For infrastructure developers, that demand can provide the baseline utilisation around which additional capacity is built.

But localisation is not demand creation by itself

There is an important caveat.

Mandating that data be hosted locally does not automatically create a competitive infrastructure market.

If domestic capacity is significantly more expensive, less reliable or technically inferior to alternatives elsewhere, localisation requirements can simply transfer the additional cost to the companies required to comply.

The stronger proposition is therefore not merely to require workloads to remain in Africa, but to create local infrastructure that businesses would choose to use even without a mandate.

That requires competitive data centre capacity, reliable electricity, strong connectivity, cloud availability, cybersecurity, technical skills and predictable regulation.

Data sovereignty can help aggregate demand. It cannot substitute for infrastructure competitiveness.

Demand exists. Affordability determines how much of it can be captured

At the other end of the market is another constraint: affordability.

Mugo Kibati, Chief Executive Officer of Telkom Kenya, argued during the discussion that the appetite for digital services among young Africans is clear, but affordability remains a major barrier to converting that appetite into greater usage.

The challenge extends beyond the cost of connectivity to the devices through which people access it. Affordable smartphones remain essential to bringing more Africans online and increasing the intensity with which existing users consume digital services.

 A network can pass millions of potential customers without generating enough revenue per user to justify continued investment. A fibre route can reach a community where relatively few households can afford fixed broadband. Mobile coverage can exist while device affordability prevents users from migrating to higher-value services.

Africa therefore faces two demand challenges simultaneously.

At the enterprise and government level, it needs sufficiently large anchor workloads to support major infrastructure investments.

At the consumer level, it needs to make devices, connectivity and digital services affordable enough to convert population and coverage into actual consumption.

$300m is still a fraction of what Africa needs

The scale of the investment requirement illustrates why bankability matters.

During the discussion, Chris Wood, CEO of WIOCC Group, addressed the company’s recently announced $300 million investment and what it means in the context of Africa’s wider infrastructure requirement.

His assessment was straightforward: when attempting to build at continental scale, $300 million does not come close to delivering everything Africa needs.

Part of the investment is expected to go into expanding existing data centre capacity, with Wood identifying Nigeria and South Africa among markets where WIOCC sees significant demand.

The point is not that $300 million is insignificant.

It is that Africa’s infrastructure requirements are considerably larger.

Mobilising that level of capital repeatedly requires investable projects capable of delivering returns. Infrastructure investors may accept long development horizons, but they still need confidence that assets will eventually achieve sufficient utilisation.

This is why the conversation about Africa’s digital infrastructure deficit cannot stop at how much money the continent needs.

The more important question is what makes that money investable.

Need does not equal capital flow

The distinction was also articulated during ITW Africa’s discussions with government and investors: need does not equal capital flow.

Infrastructure investment requires bankability, predictable rules, stable demand and confidence that projects can be delivered and operated successfully.

Africa unquestionably needs more digital infrastructure.

But infrastructure deficits do not automatically produce infrastructure investment.

A country can desperately need more fibre without presenting commercially viable routes. It can need more data centres without having sufficient contracted workloads. It can want hyperscale cloud regions without providing the power, connectivity, regulatory environment or customer base necessary to support them.

This is where Africa’s digital infrastructure debate needs to evolve.

For years, much of the continent’s investment narrative has been built around future potential: population growth, rising internet penetration, urbanisation and an expanding digital economy.

Those fundamentals remain important.

But as the capital requirements increase, investors will increasingly ask harder questions about utilisation, revenue and returns.

From potential demand to contracted demand

Africa’s digital buildout now requires a deliberate strategy for turning economic activity into infrastructure demand.

Governments can aggregate public-sector cloud requirements rather than allowing workloads to remain fragmented across ministries and agencies. Banks and other regulated industries can provide substantial domestic workloads. Large enterprises can accelerate cloud adoption. Governments can digitise public services, while policies that lower the cost of smartphones and connectivity can deepen consumer usage.

None of these interventions works independently.

Together, however, they can create the utilisation that gives investors confidence to build.

Africa’s population will continue to grow. Its economies will become more digital. More Africans will use cloud-based applications, financial services, streaming platforms and AI tools.

The demand story is real.

The challenge now is converting that demand into customers and workloads that infrastructure investors can finance.

Because for the next phase of Africa’s digital buildout, the most important number may not be how many people are online.

It may be how much infrastructure they can economically support.
